title: Three unusual sesquineolignans from Alpinia conchigera.
abstract: Three unusual sesquineolignans conchignans A, B, and C, together with two known compounds vanillin and phloroglucinol, were isolated from the whole plants of Alpinia conchigera. Their structures were established by spectroscopic analysis, including 2D NMR spectroscopic techniques.
